Patented Nov. 28, 1905.

Application filed May 18. 1904. Serial No. 208,523.

My invention relates to machinery for creasing heavy paper or cardboard such as is used in the manufacture of paper boxes, my object being to provide improved means for effecting such creasing or scoring and also effecting the severance of the sheet into blanks and for the proper scoring of such blanks in connection with the severing mechanism.

' The nature of my improvements will be best understood as described in connection with I the drawings, in which they are illustrated,

and in which- Figure 1 is a planview of the machine embodying my improvements in what I believe to be their best and most efiicacious form. Fig. 2 is a side elevation; Fig. 3, a side elevation taken as on the line 3 3 of'Fig. 1; Fig. 4, a side elevation, on a larger scale, of the creasing devices forming part of the machine; Fig. 5, a front elevation of said creasing devices; Fig. 6, a plan of the upper die; Fig. 7, a plan of the lower die. Fig. 7 is a detached perspective view of a movable plate forming part of the lower die; Fig. 8, a cross section through the dies on the line 8 8 of Fig. 4; Fig. 9, a cross-section through the dies on the line 9 9 of Fig. 4, Figs. 10 and 11 showing the operations'performed upon the card "drives the shaft B and B board in passing through the dies of the Ina- 'B" and B to shafts indicated at B and B The gear B also engages the gear B and through that gear and the engaged gea B The gear B als actuate-s the gear B, working on the stud B.-

and through it and the gears B and B dri the shafts B and B. The gear B also communicates motion through the gears B and B to the gear-wheel B and its attached shaft B the gear B engaging the gear B on stud B and through it driving the gears B and B and their attached shafts B and B.

A'is the feed-table of the machine, A inthe proper alinement of sheets of cardboard.

O is'a transversely-extending part of the 1 framing of the machine, in which are formed transversely-extending guideways C and C communicating their slots with the face and back of the frame-section C.

D is a similarly transversely extending part of the frame, having the transverse guideway D also communicating through a slot with the face of this section of the frame;

E Earefeed-rolls situated immediately in front of the table A" and secured on the shafts B B G is a cutter-cylinder secured on 'the shaft,

B immediately below'the rotatable cutterblade H, which is secured on a slide H, vertically-movable in a guideway I, which has an ontwardly-extending arm I, through which extends the adjustable abutment-screw (indicated at 1 by means of which the vertical adjustment of the slide H is regulated. The

by the T-bolt 1 passing througlr both of them and having its head I secured in the guideway C'. It will readily be seen that by this construction the cutter can he transversely shifted at will and firmly secured in any de sired place.

E E are feed-rolls secured on the shaft B B in front of the cutter H.

F F are feed-rolls secured on the shafts B and B and acting in immediate juxtaposition to the creasing devices, to be described.

E E are feed-rolls secured on the shafts B and-B in advance of the rolls F, and Q Q are cutter-carrying cylinders secured to the shafts B and B and carrying the cutting-disks, (indicated at R and R,)Which, being of a familiar type, need not be further described.

.J indicates the adjustable support for the lower creasing-die. It is formed with a boltholey", through which extends the T-headed belt J, the head moving in the guideway D the nut acting to clamp the die-support inst the transverse framing portion D.

dicating a guide at the side of said table for 1 The die-support is also formed with a perforation J through which extends the shaft B;

To the upper end of this support J are secured the parallel die-sustaining walls,(indicated at K K,) die-plates K K being secured to the tops of these walls and shaped. as best shown in Fig. 7, so as to provide a V-shaped aperture, as shown at K, between the proximate edges of the plates. The angling-walls are indicated at K K and preferably terminate where they approach closest .to each other in parallel continuations, (indicated at K K By preference the front edges of the plates K K are curved, as indicated at K.

L is a plate of somewhat less'breadth than the space between the walls K K and having formed along the center of its upper surface the rib, (indicated at L,) preferably at its rear end, curved or bowed upward, as indicated at L This plate is normally held up in contact with the plates K by the action of springs (indicated at M M) and is held against longitudinal movement by pins k, engaging openings Z, formed in the base of the plate.

N is a slide having an outwardly-extending arm N, a bolt perforation N and preferably a rearwardly extending portion N,

which is adapted to fit in the front slot C of the guide-frame C. Vertically movable in this guideway N is the die-holding arm 0, having a horizontal forward extension 0', to which the die proper is secured. The arm 0 is formed with a bolt perforation O The vertical adjustment of the arm 0 is regulated by the set-screw N, and its horizontal adj u'stment, as well as its clamping in determined position, is effected by the T-headed bolt N the head N of which is engaged in the slot 0*.

P is the-die proper, secured on the lower faces of the arm 0 and having a downwardlyextending portion P, which at the rear end is formed with two parallel ridges P P which extend down into the widerV portion between the plates K K and embrace between them the surface P which presses down against the curved portion L of the rib L. Beginning at the points indicated at P in Fig. 6, the ribs P are cut away above the level of the portion P which is continued as a rib P, preferably slightly dovetailed, adapted to extend into the narrower portion of the V, the portions P P on each side running parallel with and over the edges of the plates K where they approach closest together.

I have indicated at S the cardboard in the process of being creased or scored, the cardboard being first bent to approximately the form indicated in Fig. 10 and then as it passes through the creasing-dies being bent to the final form. (Indicated in Fig. 11.)

S S, Fig. 10, indicate the location of the bends over the rib portion L at the wider portion of the V, and S S indicate the location of the bends in the cardboard effected at the same stage of the operation over the ribs P P",

creasing devices. The severed sheets are then drawn forward by the action of the feed-rolls E E, F F, and E E between the upper and lower scoring or creasing guides, the first operation performed upon the cardboard being to bend it to approximately the shape shown in Fig. 10, and then as the paper passes forward the lines of fold are practically reversed until the final crease or score is of the kind ,indicated in Fig. 11. It will be noticed that by this operation the cardboard is along the lines of the crease first bent in one and then in the other direction, thus effectually breaking the board and insuring a permanent score or crease, such as is desirable in the manufacture of paper boxes. The special conformations of the dies as shown in the drawings and above referred to are those found to give the best results, but may of course be departed from without variation from the real spirit and scope of my invention.

It is obviously desirable that the anglingplates K K should be adjustable to-and from each other to allow of the use of the scoringdie on cardboards of different thicknesses, and

I provide for this by using washers or shims of cardboard between fixed dies, a die over and through whichthe cardboard is passed,

.said die having anaperturge with walls approaching each other in thedirection of travel of the cardboard, and a coactingfiiehaying a tongue extending into theapertrrrefithe first' die and abgut which tongue the car dboard is progressively folded byjhe-actienof the convergingnzvalls of the first die.

2. A scoring device for cardboard having in combination with means for feeding sheets of cardboard between dies a die having a V- shaped aperture and an elastically-supported central rib lying within said aperture, and a coacting die having a tongue extending into said aperture between which and the rib aforesaid the cardboard is fed and about which the cardboard is progressively folded by the converging walls of the first die.

'3. Ascoring device for cardboard having in combination with means for feeding sheets of cardboard between dies a die provided with a V-shaped aperture and a centrally-disposed rib, and a coacting die having a tongue extending into the aperture of the first die said tongue, in the part lying in the aperture, having two -projecting ribs adapted to press the board over the edges of the rib of the first die and said tongue having also in its part lying within the narrow part of the aperture a single centrally-disposed rib the wider part of the wider part of the aperture having two projecting ribs adapted to press the board over the edges of the rib of the first die and said tongue having also, in its part lying within the narrow part of the aperture, a single centrally-disposed rib over which the board is folded by the walls of the aperture,

5. A scoring device for cardboard havingin combination with means for feeding sheets of cardboard between dies a die provided with a V-shaped aperture and a centrally-disposed elastically-supported rib havinga curved and elevated rear portion L and a coacting die having a tongue extending into the aperture of the first die, said tongue in the part lying in the wider part of the aperture having two projecting ribs adapted to press the board over the edges of the rib of the first die and .said tongue having also in its part lying within the narrow part of the aperture, a single centrally-disposed rib over which the board is folded by the walls of the aperture.
